Abstract
(EN)
Disclosed is a multi-working condition design method and device for a centrifugal rotary machine. The method comprises: calculating a maximum weight flow and a pressure ratio or lift corresponding to the maximum weight flow on the basis of system operation characteristic data of a centrifugal rotary machine and a weight (S202); and obtaining index parameters of the centrifugal rotary machine on the basis of the maximum weight flow and the pressure ratio or lift corresponding to the maximum weight flow (S204). The design method and device can improve the operation efficiency of a centrifugal rotary machine and reduce energy consumption.
